The only solution is to have a virtual private network (VPN) and choose an address in Australia. But there is the quetion of rights... It costs about $5~10 per month.
Or try to ask someone living in Australia...

Wow, I've made it! I've changed the proxy of Mozilla Firefox into Australian IP and I can watch episodes on this Australian website. It's for free - you only need to registrate on their website for free (for example by Facebook). You can also download episodes using a plug for Firefox. For example http://fvdmedia.com/fvd-quick-guide-new/ But first you need to change a proxy.

The second good information is that I've found the link to all 26 English episodes! But I understand that it's forbidden to post it here in public. If you want it, you know what to do

P.S. Before I start to watch season 3 I need to watch again season 2! I don't remamber a lot. And I hope that English version of season 4 will be released faster... If the 4th season in France will air in 2020, I hope in 2021 we will get the English voices... Maybe some petition? Or maybe French fans could help in 2020 and make subtitles or at least write summaries of the episodes in English, so people after watching French version could understand it before English voices would be released?

For long, I'm looking for someone to translate missing parts of the english website en.lescitesdor.com
especially the episodes summaries (season 2 and 3) and characters.
Interested? (even just for few pages, and there is no hurry)
